Public Hearing to Consider the Adoption of the Locally-AdoptedNonattainment Plans for the Areas Presently DesignatedNonattainment within the Sacramento Valley Air Basin as Revisionsto the State of California Implementation Plan for the Attainmentand Maintenance of National Ambient Air Quality Standards:

Public Hearing to Consider Adoption of the Sacramento Metropolitan Air Quality Maintenance Plan/Nonattainment Plan (AQMP/NAP) as a Revision to the State of California Implementation Plan (SIP) for the Attainment and Maintenance of National Ambient Air Quality Standards.

RECOMMENDATIONS

That the Air Resources Board find the oxidant and carbon monoxidecontrol plans for the Sacramento Metropolitan air qualityMaintenance Area generally acceptable for submission as a 1979Nonattainment Plan. Staff has defined additional actions whichshould be taken by the Board and by Sacramento area governmentagencies to satisfy the requirements for a 1979 plan.

SUMMARY

The Air Resources Board (ARB) is the state agency responsible forpreparing and adopting the SIP for submission to the U.S.Environmental Protection Agency (EPA). The nonattainment planunder consideration was prepared by the Sacramento Regional AreaPlanning Commission (SRAPC) in cooperation with the major localjurisdictions in the Sacramento area in response to Sections 171through 176 of the Clean Air Act. An approvable 1979 SIPrevision for a designated nonattainment area must demonstrate theattainment of national ambient air quality standards for criteriapollutants no later than December 31, 1982, except that extensionmay, under specified conditions, be requested to December 31,1987 for ozone and carbon monoxide. The Sacramento air QualityMaintenance Area (AQMA) includes Sacramento and Yolo Counties andportions of Solano and Placer Counties. The AQMA has beendesignated nonattainment for ozone, carbon monoxide, and totalsuspended particulate matter. The SRAPC has requested anextension beyond 1982 for the achievement of the ozone and carbonmonoxide standards.

The plan consists of a set of industrial, motor vehicle, andtransportation control measures to be developed and implementedby local, state, and federal government agencies. Some of thesemeasures are currently being adopted as rules of the SacramentoCounty and Placer County air Pollution Control Districts. Othermeasures, including the transportation control measures, willcontinue to be studied and will be implemented at a later date. The plan is designed to compensate for increases in emissionsassociated with the regional population growth projections.

ARB staff finds that the SRAPC plan, when amended by the Board,will meet the Clean Air Act requirements for a 1979 nonattainmentplan. Staff has identified that Sacramento local jurisdictionswill need to adopt additional control measures beyond thosecommitted to in the local plan in order to demonstrate attainmentof the ozone standard by 1987 and earlier implementation ofmeasures in the plan for carbon monoxide to demonstrateattainment of that standard by 1987. A strategy to attain thestandards for total suspended particulate will be proposed to theBoard in June in the context of the Valley TSP Plan.

Public Hearing to Consider Adoption of the Shasta CountyNonattainment Plan as a revision to the State of CaliforniaImplementation Plan (SIP) for the Attainment and Maintenance ofNational Ambient Air Quality Standards (NAAQS).

RECOMMENDATION

The Board find Shasta County unclassifiable for ozone and directthe Executive Officer to notify the EPA of such redesignation. The Board accept the ozone plan for Shasta County as amaintenance strategy and the plan be submitted to theEnvironmental Protection Agency (EPA).

The Board find modifying the Shasta County New Source Review ruleis necessary to insure maintenance of the ozone standard, anddelegate to the Executive Officer the authority to modify therule for the County if local modification does not occur.

The Board request from the EPA an 18-month extension for ShastaCounty to prepare a plan to demonstrate attainment of theSecondary standard for total suspended particulates.

SUMMARY

The Air Resources Board (ARB) is the state agency responsible forpreparing and adopting the SIP for submission to the U.S.Environmental Protection Agency (EPA). The nonattainment planunder consideration was prepared by local agencies in response toSections 171 through 176 of the Clean Air Act. An approvable1979 SIP revision for a designated nonattainment area mustdemonstrate the attainment of NAAQS for criteria pollutants nolater than December 31, 1982.

Shasta County was designated originally nonattainment for oxidantand the secondary standard for the total suspended particulates. Due to the new national 0.12 ppm ozone standard, Shasta County isno longer a nonattainment area for ozone.

The plan, as locally adopted, describes seven control measuresthat will be considered for adoption and implementation. SinceShasta County is one of the fastest growing counties in thestate, an increase in emissions is likely to cause violations ofthe standard if no control measures are adopted. Therefore,staff recommends the plan be adopted and control measures besubmitted to the EPA as part of a maintenance strategy.

Public Hearing to Consider the Tehama County Nonattainment Planas a Revision to the State of California Implementation Plan(SIP) for the Attainment and Maintenance of National Ambient AirQuality Standards (NAAQS).

RECOMMENDATION

The Board accept the ozone plan for Tehama County as aMaintenance Strategy and the plan be submitted to the EPA.

The Board defer consideration of a TSP plan for Tehama Countyuntil the Valley wide TSP plan is submitted for consideration bythe Board in June 1979.

SUMMARY

The Air Resources Board (ARB) is the state agency responsible forpreparing and adopting the SIP for submission to the U.S.Environmental Protection Agency (EPA). The nonattainment planunder consideration was prepared by local agencies in response toSections 171 through 176 of the Clean Air Act. An approvable1979 SIP revision for a designated nonattainment area mustdemonstrate the attainment of NAAQS for criteria pollutants nolater than December 31, 1982.

Tehama County was designated originally nonattainment for oxidantand the secondary standard for the total suspended particulates. Due to the new national 0.12 ppm ozone standard, Shasta County isno longer a nonattainment area for ozone.

Because a maintenance strategy to prevent future violations isdesirable, staff recommends the plan as locally adopted beaccepted and the control measures implemented as part of a"maintenance" strategy.

Colusa County was designated originally nonattainment for oxidantbased on the previous standard of 0.08 ppm. Due to the newnational 0.12 ppm ozone standard, Colusa County is no longer anonattainment area for ozone.

Because there may be increased potential for industries torelocate from nonattainment areas, staff recommends the Boardadopt the amended plan as a maintenance strategy.

Public Hearing to Consider the Butte County Nonattainment Plan asa Revision to the State of California Implementation Plan (SIP)for the Attainment and Maintenance of National Ambient AirQuality Standards (NAAQS).

RECOMMENDATION

The Board modify the Butte County Nonattainment Plan by addingcommitments to adopt acceptable rules for New Source Review,architectural coating, cutback asphalt, and degreasing.

The Board find the plan's carbon monoxide analysis adequate andsubmit as such to the Environmental Protection Agency (EPA).

The Board defer consideration of a Total Suspended Particulate(TSP) plan for Butte County until the ARB-developed Valley wideTSP plan is submitted for consideration by the Board in June1979.

SUMMARY

The Air Resources Board (ARB) is the state agency responsible forpreparing and adopting the SIP for submission to the U.S.Environmental Protection Agency (EPA). The nonattainment planunder consideration was prepared by local agencies in response toSections 171 through 176 of the Clean Air Act. An approvable1979 SIP revision for a designated nonattainment area mustdemonstrate the attainment of NAAQS for criteria pollutants nolater than December 31, 1982.

Butte County is designated nonattainment for CO, TSP, and Ox. The recent relaxation of the ozone standard to 0.12 ppm does notchange these designations.

The plan, as locally adopted, contains specific commitments toadopt and implement three stationary source control measures anda New source Review rule proposed by the Basin Control Council. Staff recommends modifying the plan to add commitments to adopttwo additional control measures as well as a degreasing and NSRrule consistent with ARB's model rules.

Staff recommends accepting the carbon monoxide analysis whichdemonstrates no further measures are necessary to attain theNAAQS.

Public Hearing to Consider the Yuba County Air Quality Plan(Nonattainment Area Plan for Ozone) as a Revision to the State ofCalifornia Implementation Plan (SIP) for the Attainment andMaintenance of National Ambient Air Quality Standards (NAAQS).

The Board defer consideration of a TSP plan for Yuba County untilthe ARB-developed Valley wide TSP plan is submitted forconsideration by the Board in June 1979.

SUMMARY

The Air Resources Board (ARB) is the state agency responsible forpreparing and adopting the SIP for submission to the U.S.Environmental Protection Agency (EPA). The nonattainment planunder consideration was prepared by local agencies in response toSections 171 through 176 of the Clean Air Act. An approvable1979 SIP revision for a designated nonattainment area mustdemonstrate the attainment of NAAQS for criteria pollutants nolater than December 31, 1982.

Yuba County's original designation of nonattainment for oxidantis maintained although the ozone standard was revised to 0.12ppm.

The plan, as locally adopted, contains specific commitments toadopt and implement two control measures and a New source Reviewrule proposed by the Basin Control Council. Staff recommendsmodifying the plan to add commitments for adoption of threeadditional measures and a NSR rule acceptable to the ARB.

Public Hearing to Consider the Sutter County Air Quality Plan(Nonattainment Area Plan for Ozone) as a Revision to the State ofCalifornia Implementation Plan (SIP) for the Attainment andMaintenance of National Ambient Air Quality Standards (NAAQS).

RECOMMENDATION

The Board modify the Sutter County Plan by adding commitments toadopt acceptable rules for cutback asphalt, architecturalcoating, and modify the New Source Review rule to make itacceptable to the Air Resources Board.

The Board defer consideration of a TSP plan for Sutter Countyuntil the ARB-developed Valley wide TSP plan is submitted forconsideration by the Board in June 1979.

SUMMARY

The Air Resources Board (ARB) is the state agency responsible forpreparing and adopting the SIP for submission to the U.S.Environmental Protection Agency (EPA). The nonattainment planunder consideration was prepared by local agencies in response toSections 171 through 176 of the Clean Air Act. An approvable1979 SIP revision for a designated nonattainment area mustdemonstrate the attainment of NAAQS for criteria pollutants nolater than December 31, 1982.

Sutter County was designated originally nonattainment for oxidantand the primary standard for total suspended particulates. Thegeographic location of Sutter County between other nonattainmentareas and the violations of the revised 0.12 ppm ozone standardrecorded at a Yuba County site immediately adjacent to SutterCounty provide the basis for maintaining the ozone nonattainmentdesignation.

The plan, as locally adopted, contains specific commitments toadopt and implement two control measures and a New source Reviewrule proposed by the Basin Control Council. Staff recommendsmodifying the plan to add commitments for adoption of threeadditional measures and a NSR rule acceptable to the ARB.
